Phusion passenger-status: what value for passenger_instance_registry_dir?

Question

I\'ve done a new install of nginx 1.6.3 and passenger 5.0.15 on Ubuntu 14.04 from source in order to add tracing components from AppNeta for my ROR 4.2 app on one of my serv

Answer 1

step one check phusion passenger is installed correctly

sudo passenger-config validate-install

"if you see an ouput saying, 'Everything is looks good :-)'" then you are fine, if not you need to reinstall phusion passenger, refer to https://www.phusionpassenger.com/library/walkthroughs/start/

step two check the phusion passenger memory status

sudo passenger-memory-stats

"if you see processes running, then that's good, if not you either have to start some passenger app, or install nginx or apache with extra library for them. For nginx you need nginx and the nginx-extras".

step three uncomment the passenger_root in the nginx.conf file (for ubuntu it's usually /etc/nginx/nginx.conf) or the apache.conf file

restart nginx or apache

sudo service nginx restart # (or systemctl restart nginx, for new version of linux such as ubuntu 15.04, CentOS7)

now you can run

passenger-status 

the error should go away now. The mostly likely output you will get is saying "Phusion Passenger is currently not serving any applications."
